Where is C#?

After making the scale program I decided I wanted to make a game using Scratch. The idea is that the name of the note comes up on the screen and the student has to then touch the corresponding note on the stave. I want to make a game which includes all the notes of the D major scale where the notes come up in a random order. So far I haven't worked out how to do that so I have made one game for each note. This is the C# game! I will post the developments as I learn more about scratch.
